Constitutive Expression of a PR10 Protein Enhances the Germination of Brassica napus under Saline Conditions
Abstract
Pathogenesis-related (PR) proteins are expressed by virtually all plants in response to pathogen infection and, in many cases, in response to abiotic stresses as well and include the PR10 family. However, the precise roles of the PR10 protein family in abiotic stress responses are not clear. In this paper we report, for the first time, that the constitutive expression of a pea PR10 gene in Brassica napus enhances their germination and growth in the presence of NaCl. Our findings are discussed within the context of PR10 protein function and their utility in engineering stress tolerant crops.

Expression of pea ABR17 cDNA in Arabidopsis thaliana improved the rate of germination under salt, cold temperature, or both conditions.
“The expression of the pea ABR17 (ABA-responsive17) cDNA, a member of pathogenesisrelated proteins (PR10), in Arabidopsis thaliana showed the improved rate of germination under salt, cold temperature, or both conditions.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
